l feeder and feed-Water heater; and its object is to provide a' device of sirn leconstiuction which when connected to a oiler will automatically` supply water thereto as needed,

' or exhaust steam.

The invention consists of a receptacle the upper end of which is connected to the steamdoine ofthe boiler, while the lower len d is connected by a water-pipe with the lower portion of the boiler. A water-inlet is disposed within the receptacle, and a coiled pipe 1s also located within said receptacle and is connected with the exhaust of anengine, so that the waste steam may be utilized for heating the water prior to its discharge into the boiler. The pipe for conveying the steam to the receptacle has a float thereon ada ted to be opened or closed automatically as tlhe water within the boiler assumes different levels, thereby admitting steam to the receptacle and equalizing the pressure upon the Water contained therein, so that the feedwater -will flow into the boiler until the Water therein will reach a predetermined level and shut off the valve in the steannpipe.

vThe invention also consists of certain other novel features of construction and ctnnbinations of parts, which will be hereinafter more fully described, and pointed out in the claim.

In the accoin anying drawing the cornbined heater an feeder is shown in section,

and the relation of the boiler and engine thereto is shown dia rarnniatically.

Referring to the rawing by numerals of reference, 1 is a boiler of any preferred construction, from the steam-dome 2 of which extends a steam-pipe 3, having one end projecting downward into the boiler and pro vided with a valve 4. The stern 5 of the valve has a oat 6, which is adapted to be raised and lowered with the level of the Water contained Within the boiler. The valve is so disposed that when the lloat is raised the pipe 3 will be closed 'and when the float swings downward to a predetermined point the pipe will be opened. Pipe 3 opens into :satelites .hay ee, ieee.

Application filed March 15, 1906. Serial No. 306,267.

the upper end of a receptacle 7, the lower end of which laconncctcd by an outlet-pipe S with the lower portion of boiler l. n check-valve 9 is located at a suitable point in pipey 3, so as to prevent outward pressure from the receptacle 7 through said pipe 3, and another check-valve l0 is suitably located in pipe 8 to prevent water'within the boiler frein backing' through the pipe into thc receptacle .7. 'It supplypipc l opens into' the up ier portion of receptacle and also has a ;ieclr-valve l2 for preventing the contents of the receptacle from being forced outward throuffh said pipe. A pipe-coil 13 is disposed within the receptacle 7, and one end is conlectf; ay pipe lll with'the exhaust of an eng and the other end has an outlet or discharge pipe l5.

In operation the pipo 3 will be normally closed, and the exhaust steam will pass through pipe 14 into the coil i3 and then out ward through pipe 15, thereby heating the feed-water, which is supplied by gravity to receptacle 7 throng-i pipe 1l. As the waterlevel within the boiler becomes lower the float 6 will cause stein 5 to swing downward, and when a predetermined point is reached the valve 4 will be opened and steam will escape through the pipe 3 into receptacle 7. The pressure within said receptacle iill then be rendered equal to that within the boiler, and the water contained within said reoeptacle will therefore flow by gravity through pipe 55 and into the boiler. 4The water-level in the boiler will therefore be raised and cause the valve 4f. to close, so as to shut olf the su )ply of steainthrou'gh pipe 3. 1Water will tlien promptly iow into receptacle 7 i'roni the pipe ll until said receptacle is illed, and the operation above described can then be repeated.Vy linpor ance is attached to the fact that waste steam is utilized for heating the feed-water prior to its discharge into the boiler, said heating being facilitated by allowing water to come into direct contact with colle through which the waste steam asses.

lf desired., the flow of steam through pipe 3 may be regulated by a hand-o erated valve instead of the float-operated va ve shown and described.

l claim-4 The combination with a boiler having a steam-dome thereon, a stearn-pipe extending into the dome, and a float-valve for opening IOO reaches predetermined levels; of a Weterrecepteele, said steam-pipe .openinff into the top of seid receptacle, e cheek-'ve ve within the outlet portion of seid steelwpipe, a Weter-supply pipe opening into the upper portion of the Water-receptacle, a oheok-va1ve therein, for proventi xettim flow ot Water after being dis'ohe-rgec into the 'rece bteele, a. WeterTipe connecting the bottom oi seid, rem ceptao e with the lower portion of the boiier, a cheek-Velve therein adjacent the boiler to reveilt eeen e of witter from the boiler, a

eatingeoi1 isposed Within the Ymte/Preceptaele `and extending between. the Witter inlet eeef/ee and outlet pipes, and means for direotin steam into seid coil, the inlet end of said e011 extending into the path of Water dischzu'ffed from the Weter-su ply pipe and the steampipe opening into tliie'reoeptacle close to seid Water-supply pipe. f A
